Next, imaging data and the like recorded on the map display terminals 405 and 407 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of data recorded when the map display terminals 405 and 407 perform imaging. The above-mentioned data recorded in the present embodiment is recorded with a configuration conforming to the DCF standard. The DCIM directory 301 is a top-level directory in which data defined by the DCF standard is stored. The 100 CANON folder 302 is a folder based on the first layer naming convention defined by the DCF standard. The total number of imaging data that can be recorded in one folder is specified, and if it exceeds that, it is necessary to create a new folder with a directory name with the numerical value of the first three characters changed and record the imaging data .
IMG — 0001. jpg 303 is imaging data generated when the imaging button 232 is pressed while the still image recording mode is designated by the mode selection dial 231. IMG_0004. The mov 304 is imaging data generated when the imaging button 232 is pressed while the moving image recording mode is designated by the mode selection dial 231. The “.loc file” in which the file name other than the extension matches each image data file (.jpg, .mov) is a file describing image position information where the image data is imaged. In the present embodiment, the imaging position information is held in the above-described “.loc file”. However, the imaging position information is incorporated into the internal DB (such as HD 202) of the map display terminals 405 and 407 or the video file itself. You may make it hold | maintain. Here, the various data shown in FIG. 4 are recorded on the recording medium inserted in the recording medium insertion slot 234, but may be recorded on the HD 202 or the like.

Next, a display method when a still image or a moving image recorded on a recording medium is expressed on a map will be described. When the map display mode is designated by the mode selection dial 231, the map display terminals 405 and 407 start the operation in the map display mode. In the map display mode, the map display terminals 405 and 407 specify the map display area to be displayed on the LCD panel 235 and its scale from the information related to the current position or the imaging data. For example, the map display terminals 405 and 407 may specify an area up to a predetermined range centered on the imaging position of imaging data such as a photograph displayed in the full screen display mode as the map display area, or the user's An area up to a predetermined range centered on the current position may be specified as a map display area. Further, the user can arbitrarily change the scale at that time. That is, the map display terminals 405 and 407 specify the scale at that time according to the user operation. Next, the map display terminals 405 and 407 refer to the “.loc file” in which the imaging position information of the imaging data is described, thereby identifying the specified map display area in the imaging data recorded on the recording medium. The imaging data imaged within is identified. This process is an example of a specifying process for specifying imaging data.
The map display terminals 405 and 407 acquire and list a set of imaging position information and imaging date / time information recorded in association with the specified imaging data. The imaging position information and imaging date / time information may be recorded on a recording medium in association with imaging data, or may be recorded on the HD 202 or the like. Next, the map display terminals 405 and 407 map the association information obtained by associating the map display area information indicating the map display area, the scale information indicating the scale, the imaging position information, and the imaging date and time information. Transmit to the data server 401. This process is an example of a transmission process for transmitting the association information to the map data server 401. The map display terminals 405 and 407 transmit the association information and also transmit a map data generation request (hereinafter simply referred to as a request) based on the association information to the map data server 401. This process is an example of a request process for requesting the map data server 401 to acquire map data. Further, when the map display terminals 405 and 407 receive the map data generated by the map data server 401, the map display terminals 405 and 407 indicate the presence of the specified imaging data at the corresponding position on the map data together with the received map data. The image is displayed on the LCD panel 235. This process is an example of a display control process. Here, the map display terminals 405 and 407 may display thumbnails on the map data in order to indicate the presence of the imaging data, or may display drawing objects such as pin icons.

FIG. 5 is a diagram illustrating an example of the data configuration of the map database 404. The map database 404 is composed of the latest map data 501 and past map history data 502. The past map history data 502 holds past map data for each age. In the case of the example of FIG. 5, the past map history data 502 holds past map data every five years, such as 2005, 2000, 1995, 1990,. However, the age of the past map data to be retained is not limited to this. For example, past map data recorded at an arbitrary time such as every year or every six months can be held as past map history data 502. The latest map data 501 is always held as the latest map data. That is, the latest map data 501 is replaced with the latest map data as the map data is updated. The latest map data 501 is map data serving as a base (background) of map data generated by the map data server 401 in response to a request for map data from the map display terminals 405 and 407.
Here, the latest map data 501 and the past map history data 502 have been described as being managed on the map database 404, but may be managed on the HD 102 of the map data server 401.

Next, the behavior of the map data server 401 will be described with reference to FIGS.
FIG. 6 is a flowchart illustrating an example of processing until the map data server 401 receives a map data request and generates a map data generation job. The CPU 101 starts a map data service related to the generation of map data, and starts accepting map data requests from the map display terminals 405 and 407 (S601). When the CPU 101 starts accepting a request for map data, the CPU 101 stands by until a request is received from the map display terminals 405 and 407 (S602). When receiving a request from the map display terminals 405 and 407, the CPU 101 determines whether or not the request is a URL-based request (S603).
When the request is not based on the URL, the CPU 101 generates a map data generation job in order to directly execute the control command in the map data generation server 403 (S605). On the other hand, if the request is based on the URL, the WWW server 402 parses the URL and generates a map data generation control command that can be interpreted by the map data generation server 403 (S604). Thereafter, the CPU 101 generates a map data generation job to execute the generated map data generation control command (S605). The map data generation job is executed as an individual process for each request. Then, the CPU 101 stands by until a request for the next map data is transmitted from the map display terminals 405 and 407 (S602).

FIG. 7 is a flowchart illustrating an example of processing in which the map data server 401 executes map data generation jobs to generate map data. When generating the map data generation job, the CPU 101 starts map data generation processing (S701). The map data generation processing in the present embodiment requires association information that associates the map display area information, the scale information, the imaging position information, and the imaging date information described above. The imaging position information and the imaging date / time information are set information corresponding to imaging data. Various types of information included in the association information are determined by control commands handled in the map display terminals 405 and 407. The CPU 101 receives the handled control command from the map display terminals 405 and 407 and determines the association information (S702).
Next, the CPU 101 specifies an acquisition condition of the latest map data 501 acquired from the map database 404 from the map display area information and the scale information included in the association information designated by the control command (S703). More specifically, the CPU 101 sets the acquisition condition such that the base map data is acquired from the latest map data 501 according to the map display area indicated by the map display area information and the scale indicated by the scale information. Identify. Subsequently, the CPU 101 specifies acquisition conditions for past map data acquired from the map database 404 from the imaging position information, imaging date / time information, and scale information included in the association information (S704). More specifically, the CPU 101 determines the imaging position indicated by the imaging position information in the past map data at the time closest to the imaging date and time indicated by the imaging date and time information among the past map data included in the past map history data 502. The acquisition condition is specified so that map data of a rectangular region having a predetermined range in the center is acquired at a scale indicated by the scale information. At this time, the size of the rectangular area of the past map data may be adjusted according to the scale. Moreover, although the shape of the area | region acquired was made into the rectangle, the shape does not need to be restricted to a rectangle, Other shapes, such as circular, may be sufficient.

The CPU 101 searches the latest map data 501 for the map data to be the base in accordance with the acquisition conditions for the latest map data 501 specified in S703 (S705). More specifically, the CPU 101 acquires map data corresponding to the map display area and scale indicated by the acquisition condition specified in S703 from the latest map data 501. Note that the map data acquired by the process of S705 is an example of first map data. Next, the CPU 101 acquires, from the past map data, map data around the imaging position where the imaging data was captured in accordance with the past map data acquisition conditions specified in S704 (S706). More specifically, the CPU 101 searches the past map history data 502 for past map data at a time closest to the imaging date and time indicated by the acquisition condition specified in S704. And CPU101 acquires the map data of the rectangular area of the predetermined range centering on the imaging position which the said acquisition conditions show from the searched past map data with the reduced scale which the said acquisition conditions show. Note that the map data acquired by the processing of S706 is an example of second map data.
The CPU 101 repeats the process of S706 as many times as the number of past map data targeted for the acquisition conditions specified in S704 (S707). Then, the CPU 101 generates map data (hereinafter referred to as superimposed map data) in which the map data acquired in S706 is superimposed at a corresponding position of the map data serving as the background acquired in S705 (S708). Note that the superimposed map data acquired by the processing of S708 is an example of third map data. The CPU 101 transmits the superimposed map data generated in S708 to the requesting map display terminals 405 and 407 as a response to the request (S709). With the above processing, the CPU 101 completes the generation processing of the map data generation job (S710).

An image of map data acquired and generated by the processing of FIG. 7 will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of map data acquired / generated in the present embodiment. FIG. 8A is a diagram illustrating an example of map data serving as a base acquired in S705. FIG. 8B is a diagram illustrating an example of past map data to be acquired in S706. FIG. 8C is a diagram illustrating an example of the superimposed map data generated in S708.
Only one image data is captured in the map display area of FIG. 8A, and the location is indicated by a push pin icon 801. For example, consider a case in which superimposed map data is generated by superimposing map data around the imaging position of a photograph taken 20 years ago on map data in a map display area centered on Tokyo Station at a scale of 1: 1000. . In this case, the CPU 101 obtains the latest map data 501 so as to obtain map data of 1920 × 1080 pixels at a scale of 1: 1000 around the coordinates of Tokyo Station (north latitude: 35 ° 40′N / east longitude: 139 ° 46′E). Search for. And CPU101 acquires the map data (map image) used as a foundation | substrate as shown to the example of Fig.8 (a).

Next, the CPU 101 specifies the coordinates indicating the imaging position of the photograph taken in the area in the map data shown in the example of FIG. 8A by the method described above, and captures the photograph from the past map history data 502. Search and obtain past map data of the closest time of day. An example of past map data acquired by this processing is shown in FIG. Then, the CPU 101 searches the past map data shown in the example of FIG. 8B for a predetermined range of map data centered on the coordinates, and superimposes it on the map data of FIG. Acquire data (map image).
Further, the CPU 101 adds the map data (map image) indicated by 802 in FIG. 8B to the area 801 that is the position of the coordinates on the map data (map image) serving as the base shown in FIG. The superimposed map data (superposed map image) shown in FIG. Reference numeral 803 in FIG. 8C indicates that map data around the imaging position at the time of imaging is superimposed and displayed on the underlying map data.
Thus, since map data around the imaging position at the time of imaging is held, the imaging position can be displayed on the topography at the time of imaging even if the topography changes due to urban development or the like. It should be noted that at least one kind of scale pattern of the above-described past map history data 502 may be retained, and may be displayed in an enlarged / reduced manner according to the scale of the underlying map data. The map data may be vector format map data.

  As described above, according to the present embodiment, when displaying imaging data collected and collected over a long period of time on a map image, even if the characteristics around the imaging position have changed over time, the imaging The user can easily grasp the features around the imaging position.

<Embodiment 2>
In the present embodiment, a display method in the case where the ages when a plurality of imaging data to be displayed are captured is greatly different will be described. The system configuration and hardware configuration in this embodiment are the same as those in FIGS. 1 to 3 described in the first embodiment.
FIG. 9 is a diagram illustrating an example of an image related to display of map data using the age slide show when the map display terminals 405 and 407 of the present embodiment are set to the map display mode. Reference numeral 901 denotes an icon indicating that there is imaging data imaged there. Reference numeral 902 denotes a scale bar operated by the user to specify the age. In the example of FIG. 9A, 2002 is designated as indicated by 903. As described above, the scale bar 902 is used for designating the age at which the map data of the imaging position is displayed. In the example of FIG. 9A, a plurality of imaging data is captured in the map display area, but there is no imaging data captured in 2002. The user can also change the age by pressing the left and right of the cross key 238 described in FIG. 3 and operating the scale bar 902.

FIG. 9B shows an example in which the age of the scale bar 902 is set to 2004 as indicated by 905. In the current map display area, as shown by the icon 904, one photograph is taken in 2004, and the map data at the image pickup position at that time is superimposed on the underlying map data. By adopting such a display method, it is possible to prevent a map of different ages from being confused and confused even when a large number of imaged data of different ages are displayed on one screen. it can.
When such display is performed on the map display terminals 405 and 407, the following two methods are used. The first method is to notify the map data server 401 of the target period of the past map history data 502 from the map display terminals 405 and 407 in the map data generation processing described with reference to FIG. In this method, the acquisition target period of past map data is limited to that for the notified target period. That is, the map display terminals 405 and 407 transmit an acquisition request for superimposed map data including the designation of the target period to the map data server 401. The second method is a method in which the map display terminals 405 and 407 select a target photo for acquiring past map data from the imaging date and time and a user operation, and transmit only the information to the map data server 401. The behavior of the map data server 401 at this time may be the same as in the first embodiment.

  As described above, according to the present embodiment, in addition to the effects described in the first embodiment, even when a large number of imaging data of different ages are displayed on one screen, maps of different ages are displayed in a disorderly manner. It is possible to prevent confusion.
